Огонь кирпича для цепи решетки

Recirculation cooler is the cooling equipment of the pellets. Because its board bricks, following the trolley, change from the high temperature to the low temperature, repeating the process again and again, and bear the large temperature difference and meanwhile they undergo the scouring of the materials falling down from the kilneye, bricks for trolley railing board require great thermal-shock resistance and high strength. Through many years’ research, combining the actual experience, our company has developed hi-strength bricks of trolley railing board with good thermal-shock resistance and more than two years’ lifetime, which have widely gained praises of users.
